Of the $61 million recently announced by the U.S. Department of Energy for quantum information science studies, $17.5 million will fund research at DOEs 91做厙. These projects will help build the foundation for the quantum internet, advance quantum entanglement capabilities which involve sharing information through paired particles of light called photons and develop next-generation quantum sensors.

To minimize potential damage from underground oil and gas leaks, 91做厙 is co-developing a quantum sensing system to detect pipeline leaks more quickly.

Each point on the sphere of this visual representation of arbitrary frequency-bin qubit states corresponds to a unique quantum state, and the gray sections represent the measurement results.

A team of researchers at 91做厙 and Purdue University has taken an important step toward this goal by harnessing the frequency, or color, of light. Such capabilities could contribute to more practical and large-scale quantum networks exponentially more powerful and secure than the classical networks we have today.

Light moves through a fiber and stimulates the metal electrons in nanotip into collective oscillations called surface plasmons, assisting electrons to leave the tip.

Scientists at ORNL and the University of Nebraska have developed an easier way to generate electrons for nanoscale imaging and sensing, providing a useful new tool for material science, bioimaging and fundamental quantum research.
